Pulse oximetry is a noninvasive, accurate, and safe method for the measurement of oxygen saturation during intravenous sedation or general anesthesia. Several factors should be considered with its use, since these variables will either alter the accuracy of the readings or may cause harm to the patient. These factors include changes in the strength of the arterial pulse, body movements, dyshemoglobinemias, plasma lipids and bilirubin, color interferences, venous pulsations, and several physical factors. Awareness of these variations will help the clinician become more knowledgeable in the use of the pulse oximeter.
脉搏血氧饱和度测定法是一种用于在静脉镇静或全身麻醉期间测量血氧饱和度的无创、准确且安全的方法。使用时应考虑几个因素，因为这些变量会改变读数的准确性或可能对患者造成伤害。这些因素包括动脉搏动强度的变化、身体运动、血红蛋白异常、血浆脂质和胆红素、颜色干扰、静脉搏动以及一些物理因素。了解这些变化将有助于临床医生在使用脉搏血氧仪时更有见识。
